Hello little one! Some people have a sleep pattern that's not the same every day, it's called an irregular sleep-wake rhythm. This might happen if someone can't sleep at night and takes naps during the day, or if they go to bed and wake up at different times every day. This can make it hard for people to get the right amount of sleep their body needs. But don't worry, there are ways to help regulate sleep patterns like keeping a consistent schedule for eating and sleeping, avoiding screens before bedtime, and making sure the sleeping environment is quiet and cozy.
